Ticks are a type of arachnid that have evolved to feast on blood. A tick bite in itself is harmless, but the bacterial and viral infections that can result range from mildly inconvenient to deadly.
The majority of human infections happen in spring and summer when the ticks go through the nymphal stage, and are the size of a poppy seed. Ticks can be hard to identify in the larval or nymphal stages.
If you find a tick attached to your skin, the best way to remove it is with a pair of tweezers, and ensure that you clean and protect the wound after. Do not squash the tick, as this can also transmit disease. Read on to learn about Lyme disease and other tick-borne diseases.
